我目前有一个Django站点在亚马逊Lightsail上运行，
我运行python manage.py collectstatic一个有所有的静态文件运行良好，但我有我的媒体文件的问题...我不能上传到我的项目。下面是我的代码
settings.py

DEBUG = False

STATIC_URL = '/static/'
STATIC_ROOT = os.path.join(BASE_DIR, 'static')
MEDIA_URL = '/media/'
MEDIA_ROOT = os.path.join(BASE_DIR, 'media/')

urls.py

if settings.DEBUG:
    urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

/opt/bitnami/apache 2/conf/虚拟主机/消息-http-虚拟主机.conf（也为消息-https-虚拟主机.conf编辑）

  </VirtualHost>

models.py

message_audio = models.FileField(upload_to='audio/', null=True)
    message_image = models.ImageField(upload_to='message-pics/', null=True)

当我尝试上传文件时，我得到“服务器错误（500）”
